If the three phase current is 5A with a power factor of 0.7 and voltage RMS supply of 130V, what is the power consumption in watts? The result is then multiplied by the voltage RMS in volts. P (W) = √3 x PF x I (A) x V L-L (V), which means that the real power in watts is calculated by multiplying the square root of three by the power factor times the phase current in amps. If the single phase current is 7A with a power factor of 0.6 and a voltage RMS of 150 V, what is the power consumption in watts?Ĭalculating the Ac three phase from Volts to Watts ![]() P (W) = PF x I (A) x V (V), which means that the real power in watts is computed by multiplying the phase current in amps by the voltage RMS in volts. If the current is 6 A and the voltage supply is 18 V, what is the power consumption?Ĭalculating the Ac single phase from Volts to Watts P (W) = V (V) x I (A), which means that the power in watts is computed by multiplication of the voltage in volts by the current in amps. In case you want to perform new conversions, you can use the ‘Reset' button which erases all data from the previous calculations. You will receive the power in results which is usually indicated below the two controls. Start by selecting the type of current which can either be the direct current (DC) or Alternating current (AC) single phase/ three phase.Įnter the voltage in volts and current in amps respectively before clicking on the ‘Calculate' button. It is used to convert the voltage in volts (V) to the power in watts (W) using the current in amps (A). What is a Blog and Why Do You Need One to Make Money Online from Your blog.Always check the electrical requirements for the item that you are installing to determine whether or not the item will require its own dedicated circuit. For example, if you attempt use a microwave, a space heater, and a vacuum cleaner at one time and all three electrical outlets being used are connected to the same circuit, you will trip the breaker requiring you to perform a reset. Understanding how the three terms relate helps with understanding the electrical requirements of an item.Īmps X Volts = Watts (Amount X Force = Workload)Įlectrical items require a certain number of watts to run, and if the total watts exceed what the circuit can handle, the circuit kills the power as a safety precaution. Amps multiplied by volts gives you the total wattage (workload). ![]() Volts are the measure of the force of the electric. Amps are simply the amount of electricity used by the item. ![]() Often you will see amps, volts and watts listed on electrical items. Electricity is described by three terms: Amps (amperage), Volts (voltage), and Watts (wattage).
